- SWIVELED RING PULLEY.

Application filed March 3, 1923. Serial No. 622,487.

This invention relates to ring pulleys such as are particularly adapted to be used in connection with curtain rods su porting curtains which are adapted to be crawn or retracted through the instrumentality of suitably arranged curtain operating cords.

An important object of the invention is to so construct a device of the class mentioned as to enable it to be readily associated L: with certain types of curtain fixtures withtions incident to the drawing or retracting of the curtain through the lnstrumentality of the curtain operating cords associated therewith. p 7 I Other objects and certain advantages of the invention willbecome apparent from the following description when taken in conne tion with the accompanying drawlngs m which-- Figure 1 is a plan View of a plurality of curtain rods with which my invention is associated.

Figure 2'is a vertical sectional View taken on line 22 of Figure 1, certain elements thereof being shown in elevation.

Figure 3 is an end view of the type of bracket shown at the left in Figure 2, the bracket being viewed from the right there- Figure 4: is a view similar to that of Figure 3 showing the bracket appearing at the right in Figure 2 and as viewed from the left therein.

In the drawings wherein .for the purpose of illustration is shown what I at present consider the preferred form of my invention, the numeral 5 indicates a suitable support such, for example, as a wlndowframe to which is secured a pair of curtain rod supports 6 of conventional design, with which is associated a curtain rod 7. The device embodying my invention makes possible the association of a second curtain rod 8 with the first mentioned rod without necessitating any change or alteration thereof, and comprises a pair of curtain rod supporting brackets 9 having feet or base portions 10, the brackets 9 being provided at their, outer ends with sockets 11 into which the ends of the rod 8 are adapted to fit. In order that the brackets 9 may be readily as sociated with the supports 6 I have provided the feet with notches 12 adapted to receive the supports 6 so that the same screws 13 which are utilized for retaining the supports 6 in position may be employed to anchor the brackets 9 in a superimposed relation upon the supports 6, as shown most clearly in Figure 1. The curtain rod 8 is adapted to carry a plurality of slidable curtain rings 14 of conventional design, adapted to suspend a pair of curtains or portieres 15 which may be drawn or retracted through the instrumentality of a curtain cord 16 so associated with the curtain rings'l4 as to effect their desired operation, as will be readily appreciated by those skilled in the art to which my invention pertains.

According to the usual practice the curtain cord is passed over pulleys which are so mounted that so-called jamming of, the curtain cord not infrequently occurs due to the fact that the pulleys are fixed with respect to their respective supports and are therefore unable to accommodate or adjust themselves to varying conditions incident to the operation of the curtain cord. To overcome this objection I have employed pulleys 17 and 18 mounted in yokes 19 and 20, respectively, which are swiveled to the depending arms 21 carried by the brackets 9. The yokes 19 and 20 are substantially identical except as to size, the yoke 20 being sufficiently wide to accommodate a pair of pulleys 18 over which the depending ends 22 of the curtain cord are adapted to operate, whereas the yoke 19 is of such size as to accommodate only a single pull y shown most clearly in Figures 2 and 3. These yokes being swiveled or pivotally connected to the depending arms 21 of the brackets 9 by means of rivets 23 and 241, respectively.

arepermitted to slightly move with respect to the arms 21 to meet varying conditions incident to the operation of the curtain cord 16. For example, under certain conditions and with certain size curtain rings 14 the yoke 19 may assume its horizontal position shown in Figure 2, whereas under other conditions and when other sizes of curtain rings are employed the pulley 17 may tend to assume a vertical position; and the same 1s equally true of the yoke 20 with which are associated the pulleys 18. This self adj ustmentof the yoke 20 to prevent jamming of the curtain cord 16 is particularly desirable when a pull or stress is applied to the depending ends 22 or the curtain cord in any other than a perpendicular orsubstantialy perpendicular line. It is not unusual for one to grasp an end of the curtain cord 16, When desiring to draw or retract the curtains 15, and exert a pull upon the cord at a relatively steep angle with respect to the vertical plane of the depending curtains 15. Under such conditions-of operation the stress exerted upon the curtain cord 16 such as to move the yoke 20 from its vertical position shown in Figures 2 and i so that the disposition of the pulley 18 will correspond to the inclination of the depending end or ends to Which the operating strain has been applied.

Having thus described my invention, I claim:

1. In combination, a support, a curtain rod support extending outwardly therefrom and carrying acurtain red at its outer end, a curtain rod bracket having a foot pro vided with a notch within which said curtain rod support is received. means for se curing said foot to said curtain rod support, a second curtain rod supported by said bracket, and means supported by said bracket, for operating a curtain on said second curtain rod.

2. The combination with a curtain rod support, of a curtain rod bracket having toot provided With a notch adapted to receive said support, and a pulleyysiviveled to said bracket.

3. The combination with a pair of curtain rod supports, of a pair oi brackets having feet provided With notches adapted to receive said supports, a curtain rod associated With said brackets, curtain supporting elements slidable upon said rod, a curtain cord associated with said curtain supporting elements for effecting a sliding movement thereof uponsaid rod, yoke supporting arms carried by said brackets, pulleys over which said curtain cord is adapted to operate, said pulleys being swiveled to said arms whereby seir" adjustment thereof is permittedto meet varying conditions incident to the operation 01 said curtain cord.

at. The combination with a pair of curtain rod supports, of a pair of brackets having feet provided with notches adapted to receive said supports, a curtain rod associated with said brackets, curtain supporting elements slidable upon said rod, a curtain cord associated with said curtain supporting elements for eii ecting a sliding movement thereof upon said rod, yoke supporting arms carried by said brackets, yokes SWlVQlBCl to said arms, pulleys associated with said yokes and adapted to receive said curtain cord, said pulleys being adapted for self adjustment by reason of the swivel connection tween said yokes and brackets tomeet vary ing conditions incident to the operation of said curtain cord.

5. The combination With a curtain rod support, of a curtain rod bracket having a foot provided with a notch adapted to receive said support, an arm carried by said bracket, and a pulley sWiveled to said arm.

In testimony whereof, I have attired my signature to this specification.
